Peptides are the building blocks of protein. They’re in every cell of your body and perform a variety of functions, depending on their configuration and what you want them to do. Some peptides work as hormones and regulate vital functions like blood sugar, bone and muscle regeneration, appetite control, and sleep regulation.
Others help the skin. Peptides boost hydration and elasticity by fueling collagen, elastin, and hyaluronic acid production, softening laugh lines and wrinkles, and leaving skin firmer and plumper. They’re also great for minimizing the appearance of pores, soothing irritation, and reducing redness.
Peptide supplements have become a force to be reckoned with in high-tech cosmetics in recent years. They’re often injected in a clinic or beauty salon, but can also be applied topically. Orally administered peptides are broken down into amino acids in the gut, and aren’t as effective as their injectable counterparts.
The majority of peptides are derived from proteins, so they’re safe for most healthy adults. However, it’s always best to talk to a healthcare professional before using any supplement. Especially if you have any preexisting medical conditions or are taking any medications.
Some peptides are made from natural proteins (like whey or fish), while others are synthetic. Generally, synthetic peptides are safer than their natural counterparts because they’re less likely to cause any unwanted side effects.
Some peptides are better for skin than others, so you need to find the right ones for your needs. The best way to do that is to start by understanding what peptides do and why they’re beneficial. Once you know that, you can choose which peptides are right for you.
